Big Idea:
Prime students' brains to see the patterns again with factoring differences of perfect squares.

Each day, students complete a Warmup that usually consists of spiraling the previous day's material, in addition to older material. Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

Today's warm-up provide a "mixtape" of sorts to give kids a small amount of review daily that goes a LONG way toward retention of concepts.
